Metal Gear Solid V: The Phantom Pain’s prologue chapter, Ground Zeroes, will be given the demo treatment at the Tokyo Game Show this month, Hideo Kojima has revealed.

However, the developer has run into a big of an issue; apparently, the game’s unpredictable AI means Kojima-san is actually unable to plan the presentation in advance.

“If you’re going to see the demo at the stage event, I may have to stop [before the end of the presentation] because of errors,” the Metal Gear maestro said on Twitter (via DualShockers).

He added: “Oh my, the demo for the stage event is 100% more difficult. The behaviour of the enemy is different every time, I can’t help it because I cannot predict it. If I’m found out [by the enemy] while playing it may not be possible to complete the presentation as planned. If it was our own booth, extending the time would be possible on a case-by-case basis, but this time it’s not.”

Metal Gear Solid V: The Phantom Pain is due out on current and next-generation systems, and introduces open world gameplay for the first time in the series. The prologue chapter, Ground Zeroes, takes place in 1975 following the events of Peace Walker, with the main game picking up nine years later.
